Merge tag 'pci-v5.5-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

  Resource management:

   - Fix boot-time Embedded Controller GPE storm caused by incorrect
     resource assignment after ACPI Bus Check Notification (Mika
     Westerberg)

     addition/removal (Benjamin Herrenschmidt)

   - Fix bridge dma_ranges resource list cleanup (Rob Herring)

     the MMIO and prefetchable MMIO window sizes of hotplug bridges
     independently (Nicholas Johnson)

   - Fix MMIO/MMIO_PREF window assignment that assigned more space than
     desired (Nicholas Johnson)

   - Only enforce bus numbers from bridge EA if the bridge has EA
     devices downstream (Subbaraya Sundeep)

   - Consolidate DT "dma-ranges" parsing and convert all host drivers to
     use shared parsing (Rob Herring)

  Error reporting:

   - Restore AER capability after resume (Mayurkumar Patel)

   - Add PoisonTLPBlocked AER counter (Rajat Jain)

   - Use for_each_set_bit() to simplify AER code (Andy Shevchenko)

   - Fix AER kernel-doc (Andy Shevchenko)

   - Add "pcie_ports=dpc-native" parameter to allow native use of DPC
     even if platform didn't grant control over AER (Olof Johansson)

  Hotplug:

   - Avoid returning prematurely from sysfs requests to enable or
     disable a PCIe hotplug slot (Lukas Wunner)

   - Don't disable interrupts twice when suspending hotplug ports (Mika
     Westerberg)

   - Fix deadlocks when PCIe ports are hot-removed while suspended (Mika
     Westerberg)

  Power management:

   - Remove unnecessary ASPM locking (Bjorn Helgaas)

   - Add support for disabling L1 PM Substates (Heiner Kallweit)

   - Allow re-enabling Clock PM after it has been disabled (Heiner
     Kallweit)

   - Add sysfs attributes for controlling ASPM link states (Heiner
     Kallweit)

   - Remove CONFIG_PCIEASPM_DEBUG, including "link_state" and "clk_ctl"
     sysfs files (Heiner Kallweit)

   - Avoid AMD FCH XHCI USB PME# from D0 defect that prevents wakeup on
     USB 2.0 or 1.1 connect events (Kai-Heng Feng)

   - Fix incorrect MSI-X masking on resume and revert related nvme quirk
     for Kingston NVME SSD running FW E8FK11.T (Jian-Hong Pan)

   - Always return devices to D0 when thawing to fix hibernation with
     drivers like mlx4 that used legacy power management (previously we
     only did it for drivers with new power management ops) (Dexuan Cui)

   - Clear PCIe PME Status even for legacy power management (Bjorn
     Helgaas)

   - Fix PCI PM documentation errors (Bjorn Helgaas)

   - Use dev_printk() for more power management messages (Bjorn Helgaas)

   - Apply D2 delay as milliseconds, not microseconds (Bjorn Helgaas)

   - Convert xen-platform from legacy to generic power management (Bjorn
     Helgaas)

   - Removed unused .resume_early() and .suspend_late() legacy power
     management hooks (Bjorn Helgaas)

   - Rearrange power management code for clarity (Rafael J. Wysocki)

   - Decode power states more clearly ("4" or "D4" really refers to
     "D3cold") (Bjorn Helgaas)

   - Notice when reading PM Control register returns an error (~0)
     instead of interpreting it as being in D3hot (Bjorn Helgaas)

   - Add missing link delays required by the PCIe spec (Mika Westerberg)

  Virtualization:

   - Move pci_prg_resp_pasid_required() to CONFIG_PCI_PRI (Bjorn
     Helgaas)

   - Allow VFs to use PRI (the PF PRI is shared by the VFs, but the code
     previously didn't recognize that) (Kuppuswamy Sathyanarayanan)

   - Allow VFs to use PASID (the PF PASID capability is shared by the
     VFs, but the code previously didn't recognize that) (Kuppuswamy
     Sathyanarayanan)

   - Disconnect PF and VF ATS enablement, since ATS in PFs and
     associated VFs can be enabled independently (Kuppuswamy
     Sathyanarayanan)

   - Cache PRI and PASID capability offsets (Kuppuswamy Sathyanarayanan)

   - Cache the PRI PRG Response PASID Required bit (Bjorn Helgaas)

   - Consolidate ATS declarations in linux/pci-ats.h (Krzysztof
     Wilczynski)

   - Remove unused PRI and PASID stubs (Bjorn Helgaas)

   - Removed unnecessary EXPORT_SYMBOL_GPL() from ATS, PRI, and PASID
     interfaces that are only used by built-in IOMMU drivers (Bjorn
     Helgaas)

   - Hide PRI and PASID state restoration functions used only inside the
     PCI core (Bjorn Helgaas)

   - Add a DMA alias quirk for the Intel VCA NTB (Slawomir Pawlowski)

   - Serialize sysfs sriov_numvfs reads vs writes (Pierre Crégut)

   - Update Cavium ACS quirk for ThunderX2 and ThunderX3 (George
     Cherian)

   - Fix the UPDCR register address in the Intel ACS quirk (Steffen
     Liebergeld)

   - Unify ACS quirk implementations (Bjorn Helgaas)

  Amlogic Meson host bridge driver:

   - Fix meson PERST# GPIO polarity problem (Remi Pommarel)

   - Add DT bindings for Amlogic Meson G12A (Neil Armstrong)

   - Fix meson clock names to match DT bindings (Neil Armstrong)

   - Add meson support for Amlogic G12A SoC with separate shared PHY
     (Neil Armstrong)

   - Add meson extended PCIe PHY functions for Amlogic G12A USB3+PCIe
     combo PHY (Neil Armstrong)

   - Add arm64 DT for Amlogic G12A PCIe controller node (Neil Armstrong)

  Marvell ARMADA 3700 / Aardvark host bridge driver:

   - Use LTSSM state to build link training flag since Aardvark doesn't
     implement the Link Training bit (Remi Pommarel)

   - Delay before training Aardvark link in case PERST# was asserted
     before the driver probe (Remi Pommarel)

   - Fix Aardvark issues with Root Control reads and writes (Remi
     Pommarel)

   - Don't rely on jiffies in Aardvark config access path since
     interrupts may be disabled (Remi Pommarel)

   - Fix Aardvark big-endian support (Grzegorz Jaszczyk)

  Marvell ARMADA 370 / XP host bridge driver:

   - Make mvebu_pci_bridge_emul_ops static (Ben Dooks)
